I thought this was a pretty creative game. I thought it would be a defense game because of the title. I don't really even know why. Anyway, it annoyed me at first how you could not aim properly to hit the enemy, but then I realized you could just jump up and hit him. I was a bit angry by the fact that you couldn't seem to see how close you were to killing an enemy, but I was wrong. When there's a puff of smoke, you're there.
It could have had more in terms of environment and level design, but still good. The graphics are really nice and everything moves pretty smoothly. I never would have thought bubbles would be a weapon used by a blueberry. Oh well, nonsensical is how I like things. The sound effects were good too.
